摘要： This document discusses, among other things, a reference voltage generator circuit coupled to a plurality of fuse read circuits. The reference voltage generator circuit can be configured to mirror a reference current to produce a reference voltage and a gate bias voltage. The plurality of fuse read circuits can each be coupled to the reference voltage generator circuit and can also be coupled to a fuse of a plurality of fuses. Each fuse read circuit of the plurality of fuse read circuits can be configured to mirror the reference current using the gate bias voltage to produce a fuse read voltage across each fuse coupled to the plurality of fuse read circuits. Each fuse read circuit of the plurality of fuse read circuits can compare the fuse read voltage of each fuse and the reference voltage and can indicate a state of each fuse coupled to each fuse read circuit using the comparison.
